FROM A.D. 1815 TO A.D. 1891. 








TA 57 js 




OWING to the large number of specifications which have been 
filed at the Patent Office, it is extremely difficult for inventors 
of the present day to ascertain if their inventions have been 

It is hoped that those interested in the subject of Aero- 
nautics will find this work of benefit to them in their 
researches, though it must not be expected that all the 
information contained in the specifications is comprised in so 
small a volume. 

In the yearly indexes published by H.M. Patent Office, 
many inventions are included under the heading " Aero- 
nautics" which do not particularly refer to the subject. 
This error in the official indexes is partly the fault of 
inventors who wish to cover an enormous ground under one 
Patent. Say, for example, an inventor patents a new motor, 
and states in his specification that the said motor may be 
employed for driving locomotives, traction-engines, ships, 
balloons, etc. The Government would probably place that 
invention under each of the separate titles, comprising the 
apparatus to which the motor could be applied. No doubt 
this is the best way to evade unnecessary responsibility in 
compiling such indexes ; but in a work of this condensed 
description it would be impracticable to follow their example, 
as the reader searching for improvements in aerial machines 


would hardly appreciate a light sprinkling of traction-engines 
or ironclad war-ships. 

Many of the specifications describe inventions which are 
no doubt impracticable ; some are even ridiculously absurd 
and are probably the result of dreams. All these, however, 
are equally included with the ingenious inventions, as in 
weeding them from the remainder we should make the work 
incomplete and therefore of little value. Besides, many 
practical suggestions may be gleaned from the most absurd 
inventions; and is it not premature to criticize a question 
which is still unsolved ? 

It is to be hoped that so many failures will not deter 
inventors from still striving to master the great problem of 
aerial navigation ; for it should be remembered that aerial 
navigation is not an impossibility but only a difficulty, which 
may be mastered by careful study and perseverance. 



A.D. 1815. No. 3909. 

PAULY, Samuel John, and EGG-, Durs. 


ROUND bodies being unfit for navigation through a fluid, a 
fish-shaped aerostat is employed. The net is attached to a 
frame round the lower part of the aerostat, and the belly of 
the balloon is attached to this frame by a ribband or other 
appendage to enable same to act as a parachute, in case of 
the balloon bursting. The car is suspended to the frame. 

Wings are described composed of a head-piece playing 
backwards and forwards horizontally, and provided with 
feathers formed of silk, fixed to one side of a rod by means 
of ribs of whalebone. Five of these feathers may form a 
wing, and have their silk edges toward the tail. These wings 
will draw the air from the nose of the balloon, and drive it 
along its sides to the tail, thus causing the forward motion. 
They may also produce an upward or downward motion. 

The tail is of similar construction to the wings, and any 
motor may be employed. 

A barrel is suspended below the car, which, when moved 
toward the tail, causes the nose to rise, and when moved 
toward the nose depresses same ; thus the balloon proceeds 
upwards or downwards, as the case may be, in an inclined 
direction. Water contained in the barrel may be used as 
ballast. The inventors state that the aerostat might be 
dispensed with. 

A.D. 1826. No. 5420. 

VINEY, James, and POCOCK, George. 


KITES are employed for drawing vessels, etc., or for raising 
persons in the air. 

Tl^e/ peculiarities of these kites are: They are fitted with 
joints in the wings and the standard so that they may be 
^ojdod^p' '; Kje wings are spread by a moveable distender. 
'There are' Tour lines for controlling their power or diverting 
their course. Kite after kite may be attached one behind 
the other, and thus an indefinite power is obtained. 


A.D. 1840. No. 8337. 

POOLE, Moses. (A Communication.) 


THE inventor describes a screw-propeller having from two 
to twelve blades, which may be set at from one to eighty, 
nine degrees, according to " the power of wind you have to 
act against." 

This screw is shown in the two sheets of drawings, in 
conjunction with a boat or car. 


A.D. 1842. No. 9478. 

HENSON, William Samuel. 

THIS invention describes the employment of an " aero- 
plane " for mechanical flight. 

In the introductory part of the specification the inventor 

states : " If any light and flat or nearly flat article be pro- 
jected or thrown edgewise in a slightly inclined position, 
the same will rise on the air till the force exerted is ex- 
pended, when the article so thrown or projected will descend; 
and it will readily be conceived that if the article so pro- 
jected or thrown possessed in itself a continuous power or 
force equal to that used in throwing or projecting it, the 
article would continue to ascend so long as the forward part 
of the surface was upwards in respect to the hinder part, and 

that such article, when the power was stopped or when the 
inclination was reversed, would descend by gravity only if 
the power was stopped, or by gravity aided by the force of 
the power contained in the article, if the power be continued, 
thus imitating the flight of a bird." 

It will be seen from this quotation that Henson had a 
clear knowledge of the properties of what is now termed the 
" aeroplane," and he proceeds to describe a machine in which 
an " aeroplane," propelled forward at a suitable inclination 
and speed, serves as a support on the air for itself and other 
parts connected therewith. 

The car or vessel is made with a view to strength and 
lightness, and three wheels are situated below to enable it to 
run on the ground. On either side of the car is an extended 


surface, made of wood framework covered with silk and 
firmly stayed with wire, so that the two extended surfaces 
form a trussed beam of great strength and lightness. A 
horizontal tail, which can be raised or lowered, is employed 
at the stern, for the purpose of guiding the machine up or 
down, and a vertical rudder or tail is employed for steering 
to the right or left. 

Two propellers are employed to drive the machine, and 
the engine and boiler which are to drive the propellers are 
preferably placed in the bow of the car, as the weight should 
be placed forward. 

The machine is started by running down an incline, at the 
same time having the propellers in motion, when it will be 
found to leave the ground, and it may then proceed in any 

There should be about one square foot of surface for each 
half-pound of weight; and the following are the dimensions 
of a machine of 3,000 Ibs., which the inventor states he was 
making : Surface of the main aeroplane 4,500 square feet, 
tail 1,500 square feet, and the high-pressure steam-engine 
was of from 25 to 30 horse-power. 

This invention created a great stir at the time, and 
Mr. Henson made a machine, but it was of no practical use 
as a means of flight. 

A.D. 1843. No. 9598. 



SCREW-PROPELLER having two flat blades attached to the 
ends of a cross-bar affixed to a longitudinal shaft. 

The impact of a jet of steam on the atmosphere is also 
described as a means of propulsion. The invention is illus- 
trated as applied to ships, for which it seems to be chiefly

POTTS, Lawrence Holker. 


BALLOONS are employed for drawing cars on tension railways, 
by which means they hecome of greater utility than hereto- 

A machine is described consisting of treadles, handles, and 
cranks, for enabling men to utilize all their strength to 
actuate wings and oars. 


A,D. 1843. No. 9856. 

MOAT, William Crofton. 


A MACHINE is described to be driven by manual power (though 
the inventor states he does not limit himself to this power), 
composed of an oblong framework of wood. 

Four men are shown in the drawings turning a crank, 
which rotates two frames on either side of the machine, 
carrying four " flappers " each. These flappers act on the 
air in their downward stroke, but rise edgewise in their up- 
ward movement. The flappers consist of rectangular frames 
covered with parchment, which swing from pins on the ro- 
tating frames, and legs are provided for the machine to stand 
on when on the ground. A rudder is employed to steer the

NEWTON, William Edward. ( Communicated by 
Dr. Van Hecke.) 

THIS invention is to enable balloons to take advantage of the 

. various currents of air which constantly blow in the same 
direction, or monsoons, and currents which are variable. 
These currents not being very deep it is necessary to keep 
the balloon at a constant height, and the inventor proposes to 
do this without loss of gas or ballast. 

Wings (propellers) are formed of wire rectangular frames, 
having silk stretched thereon. Two wings are mounted 
obliquely on each of four spindles, which are rotated by 
means of hand-wheels, to which they are connected by suit- 
able gearing. When rotated the wings exert a force either 
up or down ; thus the balloon may receive a force of from 
ten to fifty pounds in either direction vertically, and so be 
enabled to remain at any desired altitude. If desired, greater 
power may be employed than that of manual labour. 

A.D. 1848. No. 12337. 

BELL, Hugh. 


THIS invention describes two distinct apparatus for navigating 
the air. 

1st. A navigable balloon. 

2nd. A mechanical flying machine. 

There are also some detail improvements applicable to 
aerial machines generally, described and shown in the 

The balloon is made in an elongated form and having a 
membrane within same, below which latter air can be forced 
to keep the balloon always distended. The network is made 
of flat silk bands, which are placed longitudinally and trans- 
versely, and also diagonally if required. A single strong 
band attaches the net to the horizontal circumference of the 
balloon, which, in case of accident, would allow the lower 
membranes to rise and fill like a parachute. 

A circular valve is held up to its seat by springs and 
opened by pulling a line. 

The balloon is fitted with a framework made of metal tubes, 
to which the boat-shaped car is attached. 

One or more two-bladed propellers are employed to propel 
the aerostat. Wings having a backward and forward motion 
in conjunction with a rotary motion are described. Pro- 
pellers are described which reciprocate, and open and shut 
like an umbrella, or a hinged double shutter. A water 
grapnel is made like an umbrella, and having a rope at each 
end. Dragging it by the rope attached to the " handle " end 
of the umbrella causes the grapnel to remain full of water, 


but by pulling the other rope the grapnel is reversed and 

For mechanical flight, an aeroplane, having its sides curved 
downward, is propelled at an angle. Wheels are provided 
to enable the machine to obtain the necessary velocity, in 
order to make the ascent. Tubes are employed in the con- 
struction of this machine. 

A.D. 1849. No. 12452. 

BROWNE, John. 


A BALLOON having a car containing passengers is attached by 
means of a cord to a metal holder, which runs in contact with 
a rail situated on the ground. 

No drawings illustrate this vague specification, which also 
describes inventions for " wheel-rigged ships " and " atmo- 
spheric railways." 

A.D. 1852. No. 155. 

BROWN, David Stephens. 


THIS invention, although only described as applied to ships, 
is of interest in aeronautics, for the reason that an aeroplane 
is employed to take the weight of the ship partly off the 

The inclined plane may be employed either above the ship 
or below same. In the first position the plane will act on 
the air, whilst in the second position the water will be acted 
on. The ship may be drawn by kites or balloons. 



A.D. 1853. No. 143. 

DE MANARA, Horace. (Provisional only.) 


BALLOONS are employed to keep seats on vessels in an up- 
right position, in order to prevent sea-sickness, consequent 
on the motion of the vessel. 

A.D. 1853. No. 179. 

JOHNSON, John Henry. (A Communication.) 


AN elongated balloon supports a frame carrying the boiler 
and engines, which latter drive two pairs of paddle-wheels 
and parachute propellers. The paddle-wheels are made to 
act on the air during half their revolutions, the blades being 
feathered during the return motion. 

The parachute propellers are mounted on horizontal re- 
ciprocating shafts, and open and close alternately, the said 
shafts being actuated by eccentrics on the paddle-wheel axles. 

Horizontal sails, which may be adjusted to any angle, are 
employed to regulate the descent. Four triangular sails, 


fore and aft, prevent rolling by their resisting surface, and 
the machine may be inclined at any angle by means of two 
weights, which may be adjusted longitudinally. 
A rudder is employed for steering horizontally. 

A.D. 1853. No. 395. 

DE NORMANDY, Alphonse Rene Le Mire. 

(Partly a Communication.) 


BALLOONS are made by pouring a certain quantity of gutta- 
percha into a vessel having its interior shaped to the form of 
the required balloon. The vessel is turned in every direction 
until the interior of same is covered with a film of the solu- 
tion. In drying this film contracts, and may then be

ALDBOROUGrH, Benjamin O'Neale Stratford, Earl of. 


IN this most lengthy specification (79 pages) an aerial machine 
is described having an aerostat of elongated form. 

Wings are most minutely described, which are intended to 
act in a similar manner to those of a bird. These wings are 
made to rise slowly against springs and then descend almost 
instantaneously, thus compressing the air by percussion under 
the concave part of each wing. 

Various theories on the flight of birds are propounded by 
the inventor, and his object has been to imitate these actions 
with his artificial wings. 

A tail is described which may act as a rudder, and strike 


downward when the vessel is rising, and so compress the air 
beneath, as the inventor believes birds commonly do, especially 

The wings may be employed in a machine without an 

Any number of persons on board the aerial vessel may 
work the wings, each person working a separate wheel. 

Combinations of canes are used in all parts of the aerostat 
which require to be kept stiff, or of a sharp or angular form, 
the strength of each being suitable to its situation, and these 
strips are sewed to the material of which the envelope is 

Smoke or heated air, with or without gas, is employed, 
and long chimneys diminish the danger of fire. 

Perforated metal or wire-gauze is placed inside the chim- 
neys, which latter may be covered, or partly so, with asbestos 

Vacuum chambers, which can be acted on by currents of 
air, are described, for admitting the gas from the aerostat 
when the same has been distended by rare atmosphere at 
great altitudes, and the aerostat is divided to contain gases of 
various density. 

A " pilot boat " containing as much weight as can be 
spared from the aerial vessel, such as cordage, provisions, and 
persons, descends first, and then draws the vessel down by 
means of cords and two windlasses. Grapnels are also taken 
in the pilot boat. 

A landing-place, having a railway for receiving air-ships, 
is described, and a building is provided for their reception. 

The 24 sheets of drawings are most theoretical in their 
nature, and it is extremely doubtful if many parts of this 
invention could be made from the vague though lengthy 


A.D. 1854. No. 759. 

BOBCEUF, Pierre Alexis Francisse. (Provisional only.) 


BALLOONS are held captive by wires, which may also be 
employed for signalling or exploding matters in the balloon, 
from an electric battery situated on the ground. 

The gas in the balloon may be used for projecting missiles.

DARTIGITENAVE, Prosper Guilhaume. (Provisional only.) 


Two apparatus, similar to parachutes, are placed one above 
the other, and alternately pulled up and down. 

These parachutes are worked by steam or other suitable 
power, and when the desired height is reached the machine 
is directed by a horizontal flapper fixed on a centre, which 
may have an upward or downward inclination given to it by 
the aeronaut. Wings are provided to enable the machine to 
turn, their direction being guided by the aeronaut.

LUFF, Henry James. (Provisional only.) 


A BALLOON freighted with explosive compounds, and having 
a telegraphic communication with a vessel, is used for attack- 
ing forts and towns. 

The movements of the vessel can be directed from the 
balloon, and the movements of the vessel can bring the 
balloon to any desired position for letting down explosives. 
Plans of fortifications by photographic process may be 
obtained from the balloon, which latter may, when desired, 
be actuated from the land.

" KITES." 

THE kite-frame is composed of two laths crossing at their 
centres, and capable of being folded parallel to one another. 


The textile material which forms the sail portion is per- 
manently secured to the ends of one lath, and temporarily 
attached to the ends of the other. 

The tails are composed of flat boards, through the centres 
of which the cord passes, the said hoards presenting their 
flat faces towards the wind. 

A float attached to a mooring line may be drawn along by 
a kite ; and for signalling purposes, signals may be attached 
to the body or other part of a kite. 

A number of loops are provided on the " belly-band " of 
the kite, for attaching the main line, and thus the angle may 
be varied according to the amount of wind. 


A.D. 1855. No. 625. 

ALDBOROUGH, Benjamin O'Neale Stratford, Earl of. 


IMPROVEMENTS are described on the invention described in 
specification No 224, A.D. 1854, and forts are described for 
the reception of aerial vessels. 

Various warlike manoeuvres with aerial vessels are also 

This specification, like others by the same inventor, is very 
lengthy, and no abridgment of same can give any idea of 
the nature of the invention. Indeed, with the original speci- 
fication before them, the writers are quite unable to understand 
how the apparatus is to be manufactured from such vague

CURTIS, William Joseph. (Provisional only.) 

GUNPOWDER-GAS is employed to inflate balloons. Kites or 


wings are attached to balloons to enable same to be governed 
from land or water, and these kites and balloons may propel 
a ship. Missiles may be conveyed and discharged by an 
electric spark, conducted along the cords or connections, or 
the missiles may be discharged by clockwork attached to 
the balloon. 

A.D. 1856. No. 2062. 

ALDBOKOUGH, Benjamin O'Neale Stratford, Earl of. 


THIS specification describes improvements on inventions 
described in specifications No. 224, A.D. 1854, and No. 625, 
A.D. 1855. 

Valves in the outer aerostat admit air to same when the 
external pressure is great, and air may also be permitted to 
escape by valves at the stern. Tubes or air-channels in the 
aerostat strengthen same. 

Air-channels in the aerostat assist in steering the aerial 
vessel, and two separate aerostats may be employed, their 
lower surfaces acting as wings. 

Double curtains protect the passengers and machinery 
during bad weather ; and improved springs are described for 
actuating the wings, which latter may also be assisted in their 
movement downwards by the force of the air contained in 
the chambers above. 

Two pilot boats are employed, and elastic cables are used 
with the grapnels. 

Rotary aerostats may be employed, and the invention may 
be applied to locomotion generally. 

Fourteen sheets of drawings are appended to a seventy- 
page description, both of which are like other specifications 
by the same inventor, viz. most vague and theoretical in 
their character.

LASSIE, Jean Baptiste Justin. 

THE aerostat is made in a cylindrical form having a pro- 
jecting helical screw on its outer surface. A smaller cylinder 
is provided within the aerostat, in which latter the crew walk 

round in a similar manner to convicts in a treadmill. This 
rotates the whole aerostat, which makes the same advance in 
the air. 

The inventor proposes to make the aerostat 900 feet long, 
and 90 feet diameter. Three hundred men could be em- 
ployed, half of which number would be on duty at a time. 
According to the pitch of the screw, the speed may be fast 
or slow. 

A cut-wind is provided at the bow, and an auxiliary 
balloon having two vertical blades is employed at the stern 
for steering. 

An adjustable weight is suspended below to regulate the 
angle of the balloon. 

The descent may be performed by pumping air into 
auxiliary balloons. Spring safety-valves are employed ; and 
the aerostat may be made of iron, copper, or aluminium. 


A.D. 1856. No. 2256. 

PELLEN, Marius. 


CAOUTCHOUC prepared in England, and subjected to the 
inventor's mode of preparation, is particularly applicable to 
the manufacture of balloons. 

Varnish is composed of amilaceous substances ; such as 
enulin, lichen, gum arabic, adragant, mucilage, and vegetable 
substances mixed with some kinds of gum, sugar, gelatine, 
dextrine, glucose, albumen, collodion, submitted to a certain 
preparation " without ether of gelatinous matter, that is, of 
pure gelatine of fish skin and of glue." 

These gums are prepared with pure water diluted with 
alcohol ; they must be very limpid, and should be strained. 

The varnish is applied while the balloons are distended. 

Small balloons should be filled at a pressure of about 40 
inches of water ; and the varnish above described may suit- 
ably be employed for coating the interiors of large balloons. 

A.D. 1856. No. 2993. 

CARLINGFORD, Godwin Meade Pratt Swift, Viscount. 


THE car is in the shape of a boat, and fitted with three wheels 
beneath same, one being in front and two behind. 

Two wings of slightly concave form are fixed to the sides, 
the sustaining laths of which wings pass through the body of 
the car from one wing to the other, and thus hold them 
firmly in position. These 'wings serve the purpose of an 
" aeroplane " resting on the air, but having no movement 
imparted to them. A tail and rudder are provided, and the 
machine is propelled by means of the " Carlingford screw," 
actuated by a hand wheel and situated in the bow of the 

A sustaining surface of 25 to 30 ft. square is proposed, 


though the machine may be considerably increased in size to 
carry very superior weights, in which case, however, the 
surface need not be increased in the same proportion. This 
conclusion is arrived at for the reason that an eagle weighing 
80 Ibs. has only four times the floating surface of a rook 
weighing one pound. 

The machine may be started by suspending the stern end 
of the car by means of a trigger and cord, to the top of a 
9 ft. pole. The bow of the car is connected to two lines 
passing over pulleys on the tops of two other poles, and a 
weight is attached to the other ends of these lines. By re- 
leasing the trigger, the lines at the bow are pulled forward 
by the weight descending, and the machine receives a great 
forward velocity. The machine then becomes free, and speed 
may easily be sustained by turning the aerial screw. 

" I have proved by experiment that an aerial screw of only 
5 inches long can give a pull greater than a ten-pound 
weight suspended to a cord and drawing through a pulley ; 
and as it will only take such a small force to maintain the 
flight of the aerial chariot, that what we look upon as fabulous 
may hereafter come to pass, and that, like the chariot of 
Jupiter, we may yet behold two eagles trained to draw the 
aerial chariot. N.B. This observation may give the witty an 
opportunity of showing off." 

It is not necessary to continually turn the winch or work 
the pedal for actuating the aerial screw, as the machine can 
descend on an incline, and thus travel fifty or sixty miles 
according to the height attained.

ALDBOROUGH, Benjamin O'Neale Stratford, Earl of. 


THIS specification describes improvements on Nos. 224 and 
625, A.D. 1855, and No. 2062, A.D. 1856. 

The weight of the crew of aerial vessels and other weight 


carried by such vessels, is utilized for producing a rotary 
motion in the rotary aerostat. The application of the weight 
is also described to produce an oscillating or vibrating 
motion, or to operate wings or propellers. 

Twin hulls or cars may be employed, in which the advan- 
tages of a sharp prow and bluff prow are united. 

Curtains form a protection to the aerostat when anchored 
in an exposed position. 

Ketractile tubes, projecting downward, warn the aeronaut 
on approaching the ground ; and the aerostat may be jointed 
to the car in such a manner that the movements of the aerostat 
need not be imparted to the car.

CLAIR, Joseph Etienne Marie Jean. (Provisional only.) 


Two hollow barrels tapering towards both ends and sur- 
rounded by screw vanes, on being rotated propel the vessel 
to which they are connected.

BALBONI, Pascal. (Provisional only.) 


THE fin or propeller is formed by a triangular blade, working 
through a slot in an axle which receives a rotary motion. 
The blade receives a vibratory motion at every half revolution 
of the axle, thus moving towards the bow and performing 
another half revolution, when the same action is repeated. 

This fin, or " aile nageoire," is to supersede the paddle- 
wheel and screw now used in steam vessels. 




A.D. 1859. No. 2330. 

BRIGHT, Henry. 

Two propellers are mounted above the car of a flying machine, 
these propellers being made to revolve in contrary directions. 

This revolving of the propellers in opposite directions keeps 
the car from gyration. 

The descent is performed by reversing the propellers. 

The accompanying illustration shows the principle of this 

A.D. 1860. No. 561. 

SMYTHIES, John Kinnersley. 


A BOILER is described having a number of tubes for obtaining 
a large heating surface with a small amount of weight. 

Vaporized hydrocarbon is burnt, which is formed from 
liquid hydrocarbon, stored in a tank below the apparatus. 

The weight of the water to be carried is also reduced by 
condensing the steam and employing the said water over and 
over again. The steam is condensed by passing into a hollow 
aeroplane formed of oiled silk and stayed by steel rods. The 
steam condensing in this large condenser runs to the lower 
part of same and is then pumped back into the boiler. 


One or more pairs of wings are employed, which are 
flapped up and down by an engine, and these wings are made 
up of large feathers having a rod on one side, the other side 
being flexible. The rods slightly overlap the flexible edges 
in such a manner that on the downward stroke the wings 
beat firmly, with the exception of the last feather which bends 
to an angle. Thus the main portion of the wing supports 
the machine vertically, whilst the last feather on each wing 
gives the forward motion. 

The rider steers the machine by leaning in whatever 
direction he desires to travel,, thus changing the centre of 
gravity. Elastic legs are employed for descending. 


A.D. 1860. No. 1114. 

HENRY, Michael. (Communication by Louis Coignard.) 


JET propulsion is described with reference to ships, and the 
direction of the jet tube is adjustable to enable the force to 
be exerted in the required direction for steering. 

This jet propulsion is also applicable to the propulsion of 
balloons and aerial vessels, though it is not particularly 
described as applied thereto. 


A.D. 1860. No. 1155. 

BOYMAN, Richard Boyman. 


THIS invention describes the application of the intermittent

CIGAK-SHAPED balloon, divided into four compartments, is 
fitted with wings on either side. These wings are moveable 
on hinges which form springs, and compartments or valves 
are situated in the wings. 

Pockets are provided, connected by valves to the under 
part of the balloon, for receiving the gas from the balloon 
when the same becomes distended. The car is made suitable 
for navigation on water, and a waterproof cloth inflated with 
air is attached to its upper edge to prevent the possibility of 
an upset. Springs are also provided on the under surface of 
the boat to lessen concussion on landing. 

The apparatus ascends or advances according to the velocity 
given to the wings. 

In a modification, the inventor states that the car may 
ascend by the employment of the wings alone, and without 
the help of the balloon. 

Rudders at bow and stern are employed for steering.

A CAPTIVE balloon displays various coloured lamps in certain 
positions, and powerful lights situated below the balloon or 
on the ground may render the balloon a luminous sphere. 
When electric light is employed, the ropes may serve as 


conductors from a battery on the ground ; and when gas is 
the lighting medium, the gas may be conducted through 
tubes attached to the ropes. 

Captive balloons may be employed as lightning-conductors, 
or as " electro-substractors." 

The balloon may be steadied by kites.

Two propellers mounted on a vertical axis, one above the

propellers are made to revolve in opposite directions, thus 
exerting an upward force, whilst at the same time one 
propeller keeps the other in proper equilibrium and prevents 
the apparatus taking a gyratory motion. 

Another propeller is mounted on a horizontal shaft and 
imparts a forward motion to the machine. Vertical horizontal 
rudders are provided for steering purposes.

retorts for producing hydrogen are made to revolve, or 
stationary retorts are fitted with trays one above the other, 
through which the steam is made to circulate. 

The iron to be heated is placed on the trays, which iron, 
if in a finely divided state, can be heated in a few minutes. 
The steam is then admitted, and passing in contact with the 
heated iron is decomposed into hydrogen and oxygen, the 
former being conducted to a condenser and thence to a 


gasometer, and the latter forms a compound with the heated 

Hydrogen thus obtained may be employed for inflating

THE principle is contained in the propulsion of a plane 
against the atmosphere by means of wings shaped like the 
hoof of a calf (or any other animal), affixed to large light 
wheels, and made of firm or loose flapping and bagging 
material, the said plane being made of a wooden or iron 
framework stretched with silk. The winged wheels being 
rotated by springs, by hand, or by steam, will flap as they 
revolve and renew an impulse on the air compressed by the 
plane, faster than the said air can recede from the pressure, 
and the machine will be upborne by the air. 

The chief part of the invention lies in the rotating wings, 
which pass on the air in one half a revolution and flap as 
they pass through the other part. 

The inventor probably had some idea of mechanical flight 
by propelling an aeroplane with feathering paddle-wheels.

AN improved fire-balloon is described in this specification, and 
apparatus applicable to fire or gas balloons are also described. 
An air-heating apparatus is placed in the car of a " Mont- 
golfier" balloon, and straw or light dry wood is employed to 
obtain the required heat. Outer casings, through which air 
may circulate, are provided round the air-heating apparatus 


to prevent the radiation of heat inconveniencing the aeronauts, 
and a fire door communicates with the interior. The fire is 
supported on a perforated sheet of iron, or a trellis-work of 
iron bars, and the ash-pan, which is suspended below the 

fire, may be raised or lowered to regulate the draught. The 
air fed to the fire is admitted through a perforated truncated 
cone, and a similar cone, but inverted, is employed to conduct 
the heated air to the balloon. 

Valves regulate the draught, and a wire-gauze disk pre- 
vents sparks entering the balloon. The balloon, which need 
not be varnished, is covered with straps like an immense net, 
and a valve may be employed at the upper part of the 

It may sometimes be necessary to empty the balloon more 
quickly, so for this purpose a cutting instrument is provided 
in the upper part of the balloon, which, on being pulled by 
means of a rope, rends the balloon from top to bottom.

vided, but the rope itself takes the strain when the springs 
are stretched to their utmost.

Two large balloons are connected to a wire rope in such a 
manner that one rises whilst the other descends. The distance 
between the balloons should be about 300 yards, and the 
people in the cars are protected from the sun and rain. 

The ropes which support the balloon, the car, and the 
holding rope, are all attached to a spar on which they are free 
to turn, the car thus being maintained in a vertical position. 

In order to prevent the holding rope coming into contact 
with car in windy weather, the end of the rope may be 
divided in two and carry a frame in which the car is free to 
turn ; or two cars may be attached to the spar, and the rope 
attached between them ; or the car may have a recess from 
the side to the centre of same, and thus allow the rope to take 
any angle without tilting the car. 

The balloon is made of strong tarred fabric, lined with tissue 
paper, combined with light fabric coated with india-rubber. 

The network may be combined with the envelope, and the 
envelope thus consolidated terminates in a circular frame 
having outlet and inlet valves. 

A hyperbolical trunk allows the wind to exert an internal 
pressure when the balloon is employed in a hurricane.

of a windmill) is employed in front, and offers very little 
resistance to the wind, as it is free to turn on its axis. A 
revolving wheel, having feathered spokes, acts as a rudder, 
and the onward motion is obtained by wings which are actu-

THE inventor describes at length the state of aeronautical 
science at date of the application for this patent, and endea- 
vours to show by his arguments that aerial navigation can 

iver be accomplished by mechanical flight. The opini 
Dr. Pettigrow, the Duke of Argyll, and Dr. Arnott 


quoted, but the inventor differs from them, and maintains 
that aerial machines must displace a quantity of air of equal 
weight to the entire aerial machine with its cargo. 

It is proposed to make a machine having a steel aerostat 
and weighing in all 600 tons. The aerostat is to be cylin- 
drical with conical ends, 200 feet in diameter, and a quarter 
of a mile long ; yet the resistance will only be 5070 Ibs., 
and the propelling force 406 horse-power. 

Jet-propulsion is employed (viz. propulsion by the impact 
of a current of air), which may either be produced by a jet of 
steam, or by a blower of the rotary blower type, which is 
shown in detail in the drawings accompanying the specifi- 

The reaction-nozzles revolve so as to propel or back the

Rudders are employed, working in pairs, one fore and one 

The gas contained in the aerostat may be employed for 
heating the boilers, though, if preferred, the heating-gas may 
be stored in separate receivers. 

Water is injected into the boiler by a steam injector, which 
forces the water at a sufficient velocity to overcome the 
pressure in the boiler. 

Moveable ballast keeps the machine at the required angle. 

To anyone interested in the science of aeronautics, this 
specification is well worth careful study ; the reflections, 
opinions, and theoretical views being most elaborately written

clever man.

expansion, and a stuffing-box closes the mouth of the balloon, 
through which the valve-line passes. Tubes are connected to 
the neck of the balloon and rise upwards to elbows hung from

THE car contains the engine and boiler, and is mounted on 
wheels to enable it to run on land when starting, whilst at

The engine actuates the wings, and pillow-blocks are 
employed to oscillate the wings, so that they may strike the 
air at an angle both in the up-stroke and the down-stroke, 
thus wedging or screwing the machine through the air. 

P> lifters, which may be forced out by steam-pressure, are 

provided for giving the machine a sudden lift upwards when 

starting, or the machine may be run along on its wheels until 

"the air acting on suitable aeroplanes, set at an angle, gives

THE pressure in the boiler is regulated by a " sneap," which 
consists of two pistons connected together, one being in com- 
munication with the steam, and the other with a mercury- 
gauge. At a certain pressure, the movement of the piston 
allows the steam to escape, and a whistle which is provided 
warns the attendant. 

The flow of oil to the furnace is regulated by a piston, 
which moves in proportion to the amount of pressure in the 
boiler ; the piston-rod is connected to a valve, and thus 
diminishes the amount of oil fed to the furnace on the 
pressure in the boiler exceeding the amount required.

which apparatus, it is stated, is also applicable to propelling 
aerial vessels, though this application is not particularly de- 

Wings or flaps are hinged to a central rib in such a manner 
that they hold the water if moved in one direction, but fold 
on the rib if moved in the contrary direction. These ribs 
are attached at right angles to rods which connect similar 
cranks, so that on the rotation of the cranks the flaps hold 
the water during half a revolution, but are withdrawn from 
the water on the return half-revolution.

SMYTHIES, John Kinnnersley. 

A STEAM bird is constructed, with wings fulcrumed on the 
ends of links attached to the body of the apparatus, and these 
wings are composed of feathers which act on the air during 
their downward stroke, but rise without much resistance, 
owing to the feathers deflecting and permitting the air to 
pass between same. 

The wings are connected at their inner ends to the piston- 
rod of a steam cylinder, which in falling and rising flaps the 
wings up and down. 

The boiler is constructed with a number of small tubes to 
give a large heating surface with small amount of weight, as 
well as requiring a very small amount of water ; and the heat 


is obtained by burning vaporized hydrocarbon combined with 
a hot-air blast. The exhaust steam is condensed in a hollow 
tail, thus saving weight in the quantity of water required. 
This tail also serves the purpose of a supporting surface (t, . 

Minute details are described.

THE specification describes improvements on an invention of 
Henry Giffard's, No. 466, 1867. 

Instead of employing an elastic nock, the leading linos Mi 
made shorter, thus allowing the balloon to expand or contract 
without sagging. 

Safety-valves are employed at the lower part of iho Imlloou, 
and the nock is made of a short rigid tube having a nVxil>l<- 

A pressure-valve shows 1.1 ^ pmHsnm of l.lie gas in the 
balloon, and the mooring-cable passes through the centre of 
the car, which latter may have a double bottom for tin-, n-r.-j, 
tion of ballast &c. 

The mooring-cable is worked by steam-engines and i* 
fitted with a tension-gauge. 

The passengers enter the car by means of a foot-bri<l.: - , 
and an enclosure is provided to protect the balloon from the 
effects of bad weather.

BOULTON, Matthew Piers Watt. 

JETS of fluid are employed as the motive-power of aerial 
machines. The jet of fluid, steam for instance, issues towards 


the hinder part of the vessel, which is shaped to offer but 
small resistance to the air. 

Various kinds of jets are described, which maybe employed 
as a supporting power by passing over the upper surface 
of a plane, thus reducing the pressure on its upper side, 
or the jets may be employed for propelling aeroplanes at an 
angle, which thus perform mechanical flight. 

Mixtures of inflammable gases may be ignited in a recep- 
tacle and thus produce the required jet by its escape through 
a suitable orifice. 

Steam boilers are described having a large heating-surface. 

In order to prevent an aeroplane leaving the plane in 
which it is travelling, self-regulating mechanism is employed, 
consisting of two rudders and a balance-weight, which mecha- 
nism corrects the angle automatically.

BOULTON, Matthew Piers Watt, and IMRAY, John. 


A CYLINDER having two pistons, one working at either end of 
same, is situated in the body of the machine. The piston- 
rods are attached to a pair of wings in such a manner that on 
the pistons being driven apart, one from the other, by the 
explosion of mixed gases between them in the cylinder, the 
wings are brought down, thus effecting the flight of the appa- 
ratus. The upward movement or recovery of the wings is 
effected by the natural pressure of air beneath same caused 
by the weight of the machine. 

A secondary piston conveys the inflammable mixture be- 
tween the two main pistons, and modifications are described 
of the various parts of mechanism. 

The wings are formed of rods curved backwards and 
covered with light fabric, and these wings are capable of ad- 

A tail is employed, mounted on a universal joint, thus 
allowing of its moving vertically and horizontally for the pur- 
pose of steering and balancing the vessel.

THE apparatus consists of a T-shaped web having vertical and 
horizontal limbs, which diminish to a point at the bow. The 


horizontal web acts as an aeroplane when the machine is pro- 
pelled forwards, and there is a receptacle in the vertical web 
for a man. 

By running along the ground the machine becomes sup- 
ported on the atmosphere, and the person actuating suitable 
propeller-fins keeps the machine in motion. A rudder may 
be employed.

A BALLOON is made of metallic sheet, and provided with a tap 
at top and bottom. The air inside the balloon is heated by a 


furnace, whose chimney passes up through the centre and out 
at the top of the balloon. 

The inventor states that the air in a balloon of 200 ft. 
diameter, heated to 230 F., would have an ascending power 
of 38 tons.

BOYMAN, Richard Boyman. 


THIS specification describes improvements on the invention, 
by the same inventor, No. 3262, A.D. 1866. 

Instead of employing gas as the lifting power (in navigable 
balloons made of metal), it is proposed to rarefy the air in the 
aerostat by exhausting or heating same. Eotary pumps are 
shown for exhausting, and the machine is propelled by the 
action of a jet or jets of air on the outer atmosphere. The 
pumps are set in action until sufficient air is exhausted to give 
the required lifting power, and the machine can then be pro- 
pelled in any direction. 

When it is desired to descend, air is admitted to the aero- 
stat, which becomes heavier than the amount of air it dis- 

The aerostat is made of rings of metal with a sheet-metal 
covering to same, and is strengthened internally by stays. 
Quotations from correspondence between Professor Blanc 
and the inventor are given at great length.

THE balloon is of elongated form, having the under horizontal 
surface flat. The propellers, which consist of adjustable vanes 


capable of being feathered, may be employed for propelling, 
steering, elevating, or lowering the machine. 

A rigid platform is attached to the balloon, and the car is 
attached below the platform by rigid stays. The balloon, 
with the help of a " stay-hoop/' forms a parachute in case of 
accident, and horizontal adjustable rails act as aeroplanes. 

Compressed gas is carried to compensate for leakage, and 
steam is generated with carburetted hydrogen gas. 

Persons may descend to the ground by ladders, when the 
balloon is anchored, and the balloon need not be brought 
right down to the ground for this purpose.

A BALLOON, which is elongated with conic ends, is stated to 
be driven by the centrifugal force of the moving parts, and 
also by the application of the resistance of the air. The 
balloon is covered with an air-tight cloth, the two edges of 
which are secured to a loose frame connected with the body 
which carries the steam motor.

HUNTEE, John Morrison. 


AEROPLANES are employed for supporting the apparatus on 
the atmosphere, and the propulsion is obtained by rocket jets, 
i. e. jets impinging on the atmosphere, which jets are pro- 
duced by the combustion of gaseous hydrocarbons mixed with 
atmospheric air. 

There are two aeroplanes, one on each side of the vessel, 


mounted on their centres so that they may be adjusted in 
angle, to direct the machine up or down ; and the outer 
edges of these aeroplanes are provided with jets, pointing 
downwards, to buoy the machine up when required. 

Jets are provided at the stern to propel the machine, or 
propellers may be 1 employed having jets at the ends of their 
blades, for giving the desired rotary movement. 

By altering the direction of the bow or stern propeller, the 
vessel is turned on its axis, and so travels to the right or left, 
or this steering may be performed by steam-jets acting diago- 
nally at the bow or stern. 

The machine is started by running down hill on wheels 
which are provided for that purpose, which wheels are con- 
nected to the bodyJaY means of springs.

AN elongated balloon is divided into three compartments, the 
bow and stern compartments being for the reception of gas, 
and the centre compartment for the steam engine. 

Aeroplanes which increase in width from the bow to the 
stern are mounted horizontally on each side of the balloon, 
and a rudder having vertical and horizontal webs is employed 
for steering vertically and horizontally. 

The balloon does not contain sufficient gas to cause it to 


rise, but when the propellers are actuated the machine rises 
with the greatest ease.

HAUTE, Richard, 


THIS machine, which may be propelled by either muscular or 
steam power, is provided with an aeroplane and propelled by 
a two-bladed screw. These blades have more of their super- 
ficies on one side of their axes than on the other, and they 
may be regulated in pitch according to the speed required. 

Rudders are employed for steering, and wheels are pro- 
vided to enable the machine to move on land. 

A " balancing beak " is employed at the bow of the 
machine, which, by its momentum, ensures the passage of the 
front of the machine through the air. The machine may be 
started down a hill or by rotating the propellers.

IF a weight be attached to a rectangular plate by cords of 
equal length connected to the corners of the plate, such plate 
in falling will be pulled down vertically. Should, however, the 
cords be of unequal length, the plate will travel down on an 
incline, or if the weight be omitted and a balloon employed 
in its place the balloon will rise on an incline. 

This principle may suitably be employed to convey tor- 
pedoes of considerable weight under water, by weighting them 
to descend at an angle. On arriving at the bottom a weight 
is unhooked and they rise at an incline towards the ship. 
Flying-birds, fishes, &c., may also be made in this manner.

THE altitude of the balloon is regulated by compressing the 
gas into a reservoir contained in the car. By compressing 
the gas the balloon descends, and by allowing the compressed 
gas to escape into the balloon from the reservoir, the ascent 
is effected. 

The balloon is propelled by projecting a weight horizontally 
from the car. The weight is connected to another weight 
below the balloon by a cord, which passes over a pulley, and 
the weight in being projected hoists the second weight up to 
the car. When hoisted the second weight may be projected,

BALLOONS are propelled by paddle-wheels composed of a 
number of paddles, which are capable of turning on their 
pivots, and thus in rotating either cut through the air or 
hold same. Each paddle is provided with a projection, and 
on the paddles being rotated the projection comes in contact 
with a bar, which turns the paddle at right angles. The 
paddles are thus always feathered or edge on the wind, except 
when held in position by the bar, so that on rotation they 
only hold the fluid in one direction. 

The paddles may be made to act in any direction by ad- 
justing the bar, and thus the balloon may be propelled up or 
down, or in any other direction.

THIS machine is of the type previously patented by the same 
inventor, in which two wings are flapped up and down by 
the piston-rod of a steam-cylinder. 


The wings may have a rigid front edffe and a flexible back 
edge, and they are arranged to hold the air on the down 
stroke, but not on the up stroke. This may be accomplished 
by shortening the wing, or allowing the air to pass through 
the wing, or deflecting the wing at an angle of 30 or 40 
during the up stroke, and allowing the said wing to return to 
its normal position and hold the air during the down stroke. 

A large tail may be employed to steady the machine, and 
if made double-skinned, it may be used as a condenser to con- 
dense the exhaust steam. The machine is guided by the 
aeronaut changing his position and thus altering the centre 
of gravity.

Two guide-cords descend through the balloon from the top 
valve to the ring, and the lower valve is free to travel on these 
guide-cords. The upper valve is constructed of netting, 
covered with gas-proof material, and by pulling the above- 
mentioned material away the gas escapes, and the force of 
air caused by the rapid descent causes the lower part of the 
balloon to rise inside the upper part, and thus form a parachute.

AN elongated balloon is composed of three compartments, 
situated one above the other, the lower compartment being 
strengthened by a strong wooden framework. The second 
compartment is attached to the upper surface of the lower 
one, and the third compartment is situated above the second 
and shifts its position according to the direction of the wind. 

A fan or propeller is driven by treadle mechanism, and the 
passengers are provided with seats within a closed car. Four 
boats are carried below the car for supporting the apparatus 
should a descent be made on water.

BALLOONS are to be propelled by the reaction of jets of air 
which are forced by means of two pairs of bellows attached 
to the sides of the car. 

The sides of the bellows may act as wings, and by adjusting 
the said bellows the balloon may be propelled in any direction.

AN elongated balloon having a concave under surface is pro- 
pelled by a screw propeller actuated by treadle mechanism. 

The underside of the balloon is made rigid by means of 
metal tubing, and the upper part of the balloon is kept to the 
required shape by thin bands of steel ribbon. The fabric of 
the balloon is held down onto the frame by means of cords, 
and by loosening these cords the fabric forms a parachute. 

The car, which is elongated and very deep, is mounted on 
a keel attached to the underside of the balloon, on which keel 
it is free to slide, the centre of gravity of the balloon being 
thus adjusted. 


The propeller-blades are composed of tubular framework 
covered with canvas, and the steering is effected by means of

" KITES." 

A NUMBER of kites, with or without balloons attached at the 
rear of same, are employed for elevating passengers, &c., in 
the air, and also for towing vessels over land or water. Con- 
trolling lines are connected to the sides of the kites in order 
to control the direction of the kites as may be required. 

By connecting a balloon to the upper part of a kite the 
failure of wind will not cause it to descend.

BALLOONS and flying machines are to be propelled and sus- 
tained, partially or wholly so, by three distinct arrangements of 

1. By employing feathering paddles, which are made to 
revolve and only hold the air on one quarter of their revolution. 
The paddles, of which there are four in each set, are con- 
structed on the principle described in the abridgement of 
No. 11994, A.D. 1884, and by rotating the sets of paddles at 
varying speeds the direction of the balloon may be varied. 

Mr. Otto, who is the inventor of the bicycle which bears his 
name, seems to have embodied some of the details of his 
bicycle invention in this specification on aeronautics. 

2. The second arrangement describes a pair of wings which 
are actuated by the direct action of a piston-rod, the said wings 
cleaving the air when moving upwards and forwards, and 
employing their full acting surface in the downward motion. 

3. The third propelling arrangement consists of a chamber 
having its rear end open to the atmosphere, through which 
opening periodical sudden discharges of steam are forced. 

The car is adjustable longitudinally below the balloon, and 
side aeroplanes are employed either with or without a balloon.

MAXIM, Hiram Stevens. 

THE object of this invention is to construct a flying machine 
having great power, effectually expended ; and every part of 
the machine is constructed as lightly as possible, consistent 
with the necessary strength. 

An aeroplane, composed of tubes covered with fabric, is 
pivotted to the main frame in such a manner that it may be 
adjusted, up or down, to any required angle. 

Two propellers, constructed of spokes covered with silk, 
are mounted side by side on the frame below the aeroplane, 


and by driving these propellers at varying speeds the machine 
may be steered to the right or left. 

The propellers are driven by separate engines, supplied with 
steam from a boiler composed of comparatively large tubes 
connected together by tubes of very small diameter, thus 
giving a large heating surface ; and the heating of such 
boiler is effected by the combustion of vaporized hydrocarbon. 

A condenser, composed of flat tubes, is situated in the 
aeroplane, or the aeroplane may act as a condenser itself if 
constructed of two skins ; thus the necessity of carrying a 
large quantity of water for the boiler is obviated, as by means 
of the condenser the water may be used over and over again. 

The speed of the engines may be regulated by barometric 
means, thus enabling the machine to be kept at any required 
altitude, as by increasing the speed of the propellers the 
machine will rise, and by decreasing the speed the machine 
will descend. 

The machine is started on rails, one pair of rails being 
below the wheels and another pair a short distance above them. 
By running the machine along, it can be noticed whether the 
wheels run in contact with the upper or the lower pair of rails, 
and the required inclination of the aeroplane may thus be 
ascertained before the apparatus rises in the air. 

A modification of the invention is described, in which the 
aeroplane is fixed to the main frame, and auxiliary aeroplanes 
are pivotted at the bow and stern for the purpose of steering 
the apparatus vertically. 

The framework of the machine is built of steel tubes, 
trussed together, with the object of gaining the greatest amount 
of strength with the smallest expenditure of weight.

HOWSON, William. 

BALLOONS are employed for conveying and automatically dis- 


charging shells of either illuminating, asphyxiating, or ex- 
plosive capacity. The shells on being discharged allow of 
an escape of gas from the balloon by actuating a valve by 
means of a connecting-cord. 

A telescopic valve is described, as well as various construc- 
tions of shells and means for discharging same. 

Shells may be conveyed on the captive rope of a balloon 
by means of auxiliary balloons, and torpedoes may be employed 
in conjunction with balloons. 

Various warlike manoeuvres are described.

THIS inventor has adopted the plan described in specification 
No. 2154, A.D. 1856, in which the balloon is provided with a 
helical worm or blades, and by rotating the balloon it forms 
its own propeller. 

In the particular arrangement described, two horizontal 
balloons are mounted on a shaft, and the car is suspended 
from the centre of the shaft between the balloons. The 
balloons are rotated by gearing from the car, and they may 
be subdivided into compartments.

BALLOONS are made in two chambers, the upper one, which 
is in the shape of an inverted heart, being made of the 
ordinary fabric, and the lower chamber being constructed of 


aluminium, so as to form a rigid case. By pumping gas 
from the upper chamber into the lower one, the balloon is 
caused to descend, whilst by allowing gas to return to the 
upper chamber an ascent is effected. A cord which is attached 

to the upper part of the balloon is drawn down when the gas 
is being withdrawn, for the purpose of preventing damage 
being caused to the balloon whilst making the descent. 

A rudder is provided for steering, and a propeller is also 
shown, though no particular means for actuating same is

A RECTANGULAR framework covered with a light glazed 
material forms the lower part of a balloon ; and at the centre 
of this frame two pendulum arms are fulcrumed, at the lower 
ends of which arms a car is attached. 

A propeller is mounted on a horizontal shaft situated on 
the frame below the balloon, the said shaft being actuated by 
the aeronaut through gearing communicating with treadle and 
hand mechanism in the car. A rope is fastened to the bow 


of the frame and thence over a pulley in the car to the stern 
of the frame. By rotating the pulley, the car is adjusted in 

position below the balloon, and thus enables the balloon 
and propeller to be regulated in position up or down.

side of the halloon, are actuated by electric motors, which are 
supplied with electricity from secondary batteries. The 
propellers with their motors are mounted on a shaft, which 

enables their position to be adjusted by means of a hand 
wheel. A rod which is fulcrumed below the balloon carries a 
hollow ball at its lower end containing sand, and by adjusting
